I am currently listening to Snitch City a podcast from the Boston Globe and reporter Dugan Arnett. It is available where ever you get your podcasts. If you are interested in managing confidential informants (human sources) it is well worth a listen.
Informants making things up and police going along -Raleigh, North Carolina
Human Sources (CHIS) domestic violence and managing risk
Informants, alleged corruption and systemic failures.
A report on a case we are following closely from Carlisle, Pennsylvania, about the trial of a former police officer and his relationship with a number of confidential informants. Allegations of consensual sexual relationships, rape and the supply of heroin to an informant are all in there. While the accused guilt of innocence is, for our purposes, academic, the allegations point to a systemic failure to manage informants safely.
